提出了可应用于中低层和多高层隔震结构的近似实空间解耦方法.利用强迫解耦法、Kelly法和近似实空间解耦法对具有非经典阻尼特性的隔震结构进行了对比分析,并将结构位移响应用具有明确物理与工程意义的系列二阶标准振子位移响应与速度响应线性组合来表示.通过理论分析和算例求解可知:近似实空间解耦法具有很强的优越性和很高的计算精度,结构隔震层和顶层的位移响应最大误差仅为0.361%和1.444%,可推广应用于隔震结构的动力响应分析.
An approximate real-space decoupling method which can be applied to middle and low-rise buildings and multi-tall buildings is proposed.The isolation structure with non-classical damping characteristics is compared and analyzed by using forced decoupling method, Kelly method and approximate real space decoupling method , And the displacement response of the structure is expressed by a linear combination of the displacement response and the velocity response of a series of second order standard oscillators with a clear physical and engineering significance.According to the theoretical analysis and example solving, the approximate real space decoupling method has a strong superiority And the high precision of calculation, the maximum error of the displacement response between the structure isolation layer and the roof is only 0.361% and 1.444%, which can be widely applied to the dynamic response analysis of the isolation structure.
